Re place ments for prod ucts that can't be re paired may be avail able at a dis count. Scan-speak is creating a new line of loudspeakers called Illuminator. This new line will begin with three tweeters, a 5" and a 6" woofer. The Illuminator tweeters will be available with a 3/4" dome and 1" dome. There will be two versions of the 1" dome, one with a shallow chamber on the back (perhaps more suitable for automotive use) and one with a deeper chamber on the back. The rear chambers have been designed to reduce rear wave reflections and to act as a heat sink. The tweeters have small flange sizes for mounting in tight spaces. The tweeter motors feature neodymium ring magnets and contoured pole pieces for an open flow to the rear chamber. Both sides of the voice coil gap are lined with copper shorting rings that enable brilliant high frequency extension while reducing distortion. The Illuminator mid woofers have exceptionally long throw, producing the bass output of drivers one size up. Both the 5 1/4" and the 6 1/2" have peak a peak x-max of 10mm. This performance is achieved with a patent pending neodymium ring magnet motor that delivers a large force factor. The underhung voice coil is precision wound with CCAW ribbon wire on a titanium former for increased power handling. The vented pole piece has a contoured opening to eliminate any hint of turbulence noise. The uniquely shaped top plate and open frame ensure there is virtually no dynamic compression caused by restriction of the diaphragm back wave. We will introduce these drivers on our website as they become available. F3 Hz Price Each

2 Madisound is pleased to offer Solist, a very precise MTM speaker system. We are confident that we have a achieved a speaker that meets or exceeds the expectations of today s discerning Audiophile. The Solist is capable of delivering the most demanding passage without losing the delicacy of every nuance. The Solist has an immediacy about it that elicits excitement in the listener, yet is never fatiguing. We have listened to the Solist on both transistorized amplifiers and tube amplifiers and found both to be pleasing. The Solist is designed around the popular Scan-speak 18W/8545K carbon/paper cone 7 woofer. This 18W/8545K features a heavily damped and carbon fibre impregnated paper cone that dampens resonances normally associated with stiff cones. The magnet system is the new SD-1 system which eliminates modulation and dynamic distortion, as well as lowering clipping distortion created as the voice coil exceeds its maximum linear excursion. This woofer uses the new Fiber Glass non-conducting high temperature voice coil former, which improves bass Width 8 ¾" Height 24" Depth 13 ½" response and resolution in the midrange frequencies. A new type of rubber surround combines dynamic linearity with low coloration. The Solist high frequencies are reproduced by the D2905/9700 tweeter. The D2905/9700 tweeter which uses the same motor as the Revelator tweeter, but with the standard flange. The Revelator motor is state of the art, using SD caps and shorting rings that minimize electrical phase shift. The top plate has been carefully machined to reduce air noises and compression from behind the dome and to assist in cooling the voice coil. The hand coated textile dome is a refinement of earlier versions and also incorporates a special devise behind the dome to minimize dynamic D3004/ AirCirc 4Ω compression. The 28mm voice coil uses plastic coated aluminum wire on an aluminum voice coil former. No ferrofluid is used in the air gap. The crossover network was designed using our anechoic chamber, Audio Precision and the Linearx Leap software. The acoustical 18dB bi-wire network yields a seamless response from 40Hz to 20KHz. This Premium crossover uses some 14 awg Goertz Copper Foil inductors, Solen Polypropylene capacitors, Hovland Musicaps and Eagle resistors. The cabinets are fully assembled oak veneered MDF with solid rounded oak corners in clear coat or black painted finish. The front and back are black and the front is covered by a full black grill. You can further upgrade the cabinet by installing the Deflex damping pads to reduce cabinet resonances and cut down on internal reflections. Price per pair without cabinets $ Deflex Panel Upgrade: 10 panels and glue: Add $ Supra Classic wiring is supplied for internal wiring. Cabinets are no longer available for this speaker. The Solist The new D3004/ builds on the experience of the one-inch R29 ring radiator, resulting in low resonance frequency, but further provides the extended dispersion characteristics of a ¾-inch dome. Tymphany s unique AirCirc Magnet System named for the way it optimizes air flow within the chamber rearranges the traditional magnet structure from a single magnet to an open magnetic circuit comprised of six separate neodymium slugs. This, in combination with the chamber, results in the elimination of the reflections and resonances that compromise the performance of traditional motors.

3 R2904/ Ω The R2904/7000 tweeter is the new flagship tweeter in the Scan-speak line. This tweeter incorporates many innovative design concepts. The first notable difference is the use of a phase plug. The dome is attached to the phase plug, so the radiating area is now concentrated around the voice coil. This offers more control and reduces distortion and loss that occur at the center of the dome on dome tweeters. The phase plug also acts as a wave guide, reducing high frequency cancellations. A specially designed venting system uses a needle to cut down on turbulence in the air cavity. Better dynamics are achieved by not using ferrofluid, voice coil cooling is performed by the venting system and conduction through copper rings. The new SD-2 neodymium magnet system improves transient response.

9 D2905/9300 1" Dome Tweeter The D2905/9300 is a 1 textile dome tweeter with a very flat frequency response and low distortion. The D2905/9300 achieves a lower resonance and increased clarity by using several coatings of damping material on the dome and chambering behind the dome. Both these damping factors and the use of a light magnetic fluid, reduce the resonances as much as possible, while reducing compression affects. this tweeters linear response and openness make it a good choice for any system.
